Neighbour's phone is dead - help

on ‎06-04-201720:02

My elderly neighbour has 3 phones in his home and all are dead. When calling his number from my mobile there is a connection to the line but not to any of the phones. I've tried my home phone in his socket and that didn't work either. He has no way of contacting VM to arrange an engineer. Can someone help please? Area 30, my phone is fine.
